BMT6228 Micro-Controller Unit Subsystem

• All processor transactions go to code cache first.• If the requested content is found in TCM or in cache, no bus transaction is required• If the code cache hit rate is high enough, bus traffic and MCU can be effectively.

MT6228 TVOUT• Support NTSC/PAL interlaced TV format.• It includes two components: a TV controller and a TV encoder.

TV controller:1. Fetch the TV frame buffer.

• In video playback mode: the source is from the video codec buffer in YUV420 format.• In image playback mode: the source is in RGB565 format. Still images can be displayed.

2. Scale the frame size to fit the TV size.• In NTSC mode, the ideal display area is 720(W)x480(H). Field update rate is 59.94 frames

per second (fps).• In PAL mode, the idea display area is 720(W)x576(H). Field update rate is 50 fps.• The controller support an arbitrary image size up to 640 pixels in height and 480 pixels in

width.

TV encoder:• It receives a YCbCr stream from the video scaler and encodes the stream into NTSC/PAL

signal.

BMT6228 DAI, PCM and EDI Pin Sharing

• Beside the shared pins, the EDI interface can also use other dedicated pins. With the dedicated pin (GPIO4,5,6), PCM and EDI interfaced can operate at the same time.
